Classic Text Adventure Masterpieces of Infocom is a collection of 33 computer games from interactive fiction pioneer Infocom, and the top 6 winners of the 1995 Interactive Fiction Competition, released in 1996. It was available as a single cross-platform CD-ROM, which included PDFs of all the Infocom games' instructions, maps, and hint booklets.

The collection included all of the contents of the previous two Lost Treasures of Infocom collections except for The Hitchhiker's Guide to the Galaxy and James Clavell's Shogun. Unlike the Lost Treasures collections, though, Masterpieces included the adult game Leather Goddesses of Phobos.
